[Bluez-devel] bluetooth hardware that is discoverable by default?

[Dave West <westdwestd@yahoo.co.uk>]

Hi there,

I have very simple requirements for a bluetooth
'beacon' that is discoverable, but nothing else (ie.
it responds to discovery requests, but you don't need
to connect to it or anything).  At the moment I am
using a D-Link USB dongle where the USB powerlines are
soldered to an external power supply.  This supplies
power to the beacon, but it still needs to connect to
a linux/bluez equipped laptop (with USB power
disconnected as it draws its power externally) to
bring up the device and make it discoverable. 
Immediately disconnecting the bluez laptop you then
have a cheap standalone beacon as long as the power
remains.

I'm wondering is there any way to have a beacon like
this where you don't have to connect it to a laptop
after its been powered up to make it discoverable?  My
searches on google and looking at the bluez code make
me think that normally a HCISETSCAN ioctl is sent to
the device with SCAN_INQUIRY|SCAN_PAGE option to make
it discoverable.  My question is are there any dongles
out there that become discoverable immediately when
they are powered without having to send them a HCI
command?  One of you who have written drivers for
these things might know....

Or if there aren't, can anyone suggest another way I
might go about making or designing a cheap self
powered bluetooth beacon that is discoverable on
powerup?  I may want to manufacture these beacons in
some quantity later.

Thanks,
David
